Abstract
The adoption of grammatical modifier for implants or other kinds of biomaterials eventually absorbed by the body has been a long-standing confusing issue, and there are diverse terms in the large fields of research, which not only causes the difficulties when searching on the Internet, but also blurs the meaning and boundaries for researchers. Prior unification attempts at laws/standards set the basis for such research fields towards researching, labeling, marketing and instructions for use. Considering this, the typical grammatical modifiers “biodegradable”, “resorbable”, “absorbable”, along with their noun forms used in the decades of scientific research have been reviewed and explained, interdisciplinary in chemistry, ecology, materials science, biology, microbiology, medicine, and based on usage customs, laws, standards and markets. The term “biodegradable” has been not only used in biomaterials but also in ecology waste management, biomedicine and even natural environment. Meanwhile, the term “resorbable” has long been used in biological reaction (osteoclast driven bone resorption), but is inappropriate for implants that do not carry the potential to grow back into their original form. The term “absorbable” focuses more on the host metabolism to the foreign biodegradation products of the implanted material/device compared with the term “degradable/biodegradable”. Meanwhile the coherence and normalization of the term“absorbable” carried by its own in laws and standards contributes as well. In general, the authors consider the term “absorbable” to be the best grammatical modifier with respect to other adjectives which share the same inherence. A further internationally unified usage is proposed by us.
摘要
关于最终被人体吸收的植入材料, 领域内文献采用的英文修饰词长期以来混乱且不同, 不仅造成文献检索困难, 同时模糊了研究人 员的研究边界. 此领域在法律法规/标准中统一用词的确定, 为领域内的科学研究、产品销售及产品使用说明奠定了基础. 我们基于化学、 生态学、材料学、生物学、微生物学和药学, 立足于使用习惯、法律、标准和市场, 对领域内使用已久的典型修饰词“生物可降解”、“再 吸收”和“可吸收”进行了讨论和解释. 总的来说, 尽管目前绝大多数修饰语实际想表达的意思相同, 作者认为“可吸收”这一英文修饰语是最 恰当的修饰词. 同时, 我们提议进一步规范和统一该领域修饰词的使用.
